lug projecting therefrom, the lug being This invention relates to compositionshingles and one-of the, objects of the invention is to produce shingles which can be conveniently cut from sheets of shingle material andv which are of such shape as to present a pleasing and striking design when laid on the roof. Another object of the invention is to provide convenient and effective means for locking down the lap portion of the shingle.

Of the accompanying drawings Fig. 1 shows the method of cutting out the shingle; Fig. 2 shows a plan view of the shingles assembled; and Figs. 3 and 4 show slightly different single shingles.

Referring to the drawings the shingle has a lap 'portion 26, two slits 27, and two projections 28. The shingles are cut as indicated in Fig. 1 so that there -is no waste.

B0 They are assembled as indicated in Fig. 2 with the shingles in the same horizontal lrow spaced apart, as indicated at 29, and with another shingle overlapping the two spaced ends. A lugy 28 of one of the under- 25 l ing shingles is passed upwardly through tiie slit 27 of the overlying shingle, and, similarly, the lug 28'of the other underlying shingle is passed upwardly through the other slit 27 of the same overlying shingle. 30 In this way the lap portion 260i the overlying shingle is locked down. As another underlying shingle 31 passes upwardly a material distance under the lap 26, and also under the ends of the underlying shingles and above the slits 27, any leakage through or around the slits is prevented.

Fig. 4 shows a slight modification of this shingle in which slots 32 are used instead of slits-27, These slots having their sides spaced apart to allow the vlug to be more freely entered. The amount of lap of these shingles, as well as the shingles 25, is varied by simply varying the distance of the slits 32 or 27 from the lower edge of the shingles.

I claim as my invention: i

1.v A shingle comprising a body portion, and a 'shank portion projecting angularly therefrom, one end of the body portion having an interior slit adjacent the edge, the corresponding edge of the shank having a adapted to enter the slit of another similar shingle, the said shank projecting from said body nearer one end of the body than the other and with one edge in line with the straight edge of the body, and the said slity beingin the end of the body moreremote from the shank.

.2. A shingle comprisin a body portion, and a shank projecting rom each end of the body portion, one edge of each of the shanks being inline with and a continuation of one edge ofthe body, two s acedlu projectin from the opposite e ge of t e body, an said body having two spaced in teror slits adjacent said op osite edge and in line with the respective u and a lug projecting from the correspon ing op osite edge of each of the Shanks and being a apted to enter the said slits of adjacent shingles.

3. A shingle comprising a rectangular body portion, an a rectangular shank projectin from'each end of the body portion, one e ge of each of the Shanks being in line with and a continuation of one edge of the body, said shin le havingl two spaced interior slits in sai bod adjacent the opposite edge, and a lug projecting outwardly from the corresponding opposite edge of each of the shanks in the outer corner thereof and being adapted to enter the said slits of adjacent shingles. s

4. A roofing strip comprising a rectangular body portion and a rectangular shank projecting from o ne end of the body ortion, Aone edge of the shank being in ine with and a continuation of one ed e of the body, alu projecting outwardly om the opposite e ge of the bod said strip having anjinterior slit in said ody ad'acent said opposite edge and in line with lsaid lug, and a lug projecting from'the corresponding opposite edge of the shank adjacent the outer corner thereof and being adapted to enter the said slit of adjacent shingles.

5. vA plurality of shingles assembled on a roof, each shingle comprising a body portion, and a shank projecting from each end 'of the body portion, one edge of each of the Shanks being in line with' and a continuationl of one edge of the body, each of said shingles having two spaced interior slits adjacent the opposite edge of the body, and a lug projecting from the outer end of each of the Shanks,

5 the shingles being assembled in rows, with the adjacent shank lugs of two shingles in one row being inserted in the respective slits of an adjacent shingle in the overl row. 6. A plurality of shingles assemblled on a roof, each shingle having two spaced lugs and two spaced interior slits for receiving similar lugs, the shingles being laid in rows but with the adjacent edges of adjacent shinles in the same rows being spaced apart a istance substantially equal to the distance between the two slits in one of the shingles, and with the lugs of each shingle interlocking withthe respective slits of two adjacent shingles in an adjacent row.

' 7. A plurality of shingles assembled on a roof, each shingle having two spaced lugs and two spaced interior slits for receiving similar lugs, the shingles being laid in rows with the adjacent edges of adjacent shingles in the same rows being spaced apart, and with the lugs of each shingle interlocking with the respective slits of two adjacent shingles in an adjacent row. y

In testimony whereof, I hereunto set my hand.
